Scientists working in IVF laboratories come from varied backgrounds with a myriad of different educational experiences. Rarely are there local or national requirements which dictate the education or training needed; however, at a minimum, any aspiring embryologist will have an undergraduate degree with emphasis in biology and chemistry. A degree in laboratory sciences may offer many desirable, general laboratory skills, while an advanced degree, Masters or PhD in clinical embryology or reproductive sciences will give the scientist a stronger theoretical background. Laboratory directors and managers responsible for hiring scientists must take numerous factors into consideration when selecting candidates. Clinics with low cycle volumes will require embryologists with broader skill sets as they are likely to be responsible for all aspects of the laboratory, whereas clinics performing thousands of cycles per year may employ receptionists and technicians to manage the administrative laboratory duties so that scientists can focus on the embryology work.
